C160A01A-AAT
WINTER DRIVING
The more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:
C160B01A-AATSnowy or Icy Conditions
To drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed, it
is necessary to select tires equivalent in size
and type to the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.
NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.
C160D01A-AATCheck Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge in
your battery can be checked by your Hyundai
dealer or a service station.
C160E01A-AAT
Change to "Winter Weight" Oil if
Necessary
In some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations. If
you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160C01A-AATUse High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high quality eth-
ylene glycol coolant in the cooling system. It is
the only type of coolant that should be used
because it helps prevent corrosion in the cooling
system, lubricates the water pump and prevents
freezing. Be sure to replace or replenish your
coolant in accordance with the maintenance
schedule in Section 5. Before winter, have your
coolant tested to assure that its freezing point is
sufficient for the temperatures anticipated dur-
ing the winter. o Don't "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gear result-
ing in the engine bucking. If this happens,
shift to a lower gear. Over-revving is racing
the engine beyond its safe limit. This can be
avoided by shifting at the recommended
speeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine
power so your fuel economy is reduced
when you use it.
C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners, es-
pecially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.

6- 14 DO-IT-YOURSELF MAINTENANCE
G130B02A-AATTo Replace the Fluid
Recommended brake fluid conforming to DOT 3
or DOT 4 specification should be used. The
reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
G140A01A-AAT
AIR CONDITIONER CARE
Keeping the Condenser Clean
The air conditioner condenser (and engine ra-
diator) should be checked periodically for accu-
mulation of dirt, dead insects, leaves, etc. These
can interfere with maximum cooling efficiency.
When removing such accumulations, brush or
hose them away carefully to avoid bending the
cooling fans.
G140C01A-AAT
Lubrication
To lubricate the compressor and the seals in the
system, the air conditioner should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air con-
ditioning system is not otherwise in use.
G140B01A-AATChecking the Air Conditioner Opera-
tion
1. Start the engine and let it run at fast idle for
several minutes with the air conditioner set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your
eyes. It will also damage your vehicles paint
if spilled on it and not removed immediately.
!CAUTION:Running the air conditioning system for ex-
tended periods of time with a low refrigerant
level may damage the compressor.
!
G130A01A-AATCHECKING THE CLUTCH FLUID
To Check the Clutch Fluid
The clutch fluid level in the master cylinder
should be checked when performing other un-
der hood services. The system should be
checked for leakage at the same time.
Check to make certain that the clutch fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir. Fill as required. Fluid loss
indicates a leak in the clutch system which
should be inspected and repaired immediately.
Consult your Hyundai dealer.

DO-IT-YOURSELF MAINTENANCE 6- 15
G140D01A-AATChecking the Compressor Drive Belt
When the air conditioning is being used regular-
ly, the compressor drive belt tension should be
checked at least once a month with the engine
turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx. 8.0 mm). If the belt is too loose, have
it adjusted by your Hyundai dealer.CRANK PULLEY

CHANGING THE AIR FILTER
(For Evaporator and Blower Unit)
(If Installed)
The air filter is located in front of the evaporator
unit behind the glove box.
It helps to decrease pollutants from entering the
car and to filter the air.

2. Remove the cable and the wiring from the
filter cover.
1. Open the glove box and remove the adjust-
ing pins on both sides of the glove box.

3. Remove the filter cover by pushing the upper
end of the filter cover.
